Huge Kreem tank sealer failure!
A couple months ago we used Kreem to seal our tank. Heavliy modified and welded, we pressure tested to the point we had no leaks at about 10 pounds of air pressure. The tank was rust free, even though it was used before we started cutting on it, the tank was like new inside.
We just wanted to make sure we wouldn't have leaks develop in the future so we thought we'd seal it just to be sure.
We followed the instructions with the Kreem along with reading about anything we could get our hands on about proper usage. The coating went on without issue.
The tank had no problems and has been setting on the shelf without any plugs in it, while we finished the bike. Today we pulled it off to prep it for paint and we noticed some light surface rust had developed right at the edge of the petcock bung.
Cleaned it up with a small wire wheel and hit the tank with a light blast from the air compresser to make sure all the dust was out.
Huge pieces of Kreem came out with the back side of the chips with a rust orange color! Now the tank has a layer of surface rust, covered with what is left of the Kreem that hasn't come off as yet.
This is a HUGE problem -this tank has about 30 hours of metal work, not to mention the body work. We have to salvage this tank if at all possible.
First step is to remove the Kreem and then kill all the rust before sealing it again with something this time that won't create a nightmare.
Any suggestions on how to get rid of the Kreem and then make absolutely sure all the surface rust is nutrilized? Then what should be used to re-seal the tank?
Feeling a bit' desperate here -cannot believe the Kreem has failed and to add insult to injury leaving us with all this surface rust!
